A couple of weeks ago, I attended a series of training sessions organized by my company. For these training sessions we are provided with a company laptop. To prevent everyone from having an entirely different system, it is required to use Ubuntu as an OS. So far no problems. Everything works. I have used this laptop for over a year now, both at home and on other trainings.

Clone ubuntu for dual boot of same base system
tr flag

I have a rather complicated 18.04 LTS system for development purposes - I would like to clone the system and make it dual bootable so I can have version a for production and version b for test.

I have cloned (copied) my ubuntu partition using gparted - but update-grub and os-probe only find the initial ubuntu - not the cloned version - any ideas on how to boot into the clone?

Thanks for your help

Fixing permissions on home directory
br flag

So I was following a guide (incorrectly) and mindlessly ended up giving owner permissions to my home directory (/home/username) to a different group (or user, not sure which is which). I figured out how to get myself owner back, but now it seems like I have a bunch of messed up permissions with directories inside my home directory. For example Flatpak apps which are installed in ~/. local/share/flatpak ...

The Stunning Power of Questions

Much of an executive’s workday is spent asking others for information—requesting status updates from a team leader, for example, or questioning a counterpart in a tense negotiation. Yet unlike professionals such as litigators, journalists, and doctors, who are taught how to ask questions as an essential part of their training, few executives think of questioning as a skill that can be honed—or consider how their own answers to questions could make conversations more productive.

That’s a missed opportunity. Questioning is a uniquely powerful tool for unlocking value in organizations: It spurs learning and the exchange of ideas, it fuels innovation and performance improvement, it builds rapport and trust among team members. And it can mitigate business risk by uncovering unforeseen pitfalls and hazards.

For some people, questioning comes easily. Their natural inquisitiveness, emotional intelligence, and ability to read people put the ideal question on the tip of their tongue. But most of us don’t ask enough questions, nor do we pose our inquiries in an optimal way.

The good news is that by asking questions, we naturally improve our emotional intelligence, which in turn makes us better questioners—a virtuous cycle. In this article, we draw on insights from behavioral science research to explore how the way we frame questions and choose to answer our counterparts can influence the outcome of conversations. We offer guidance for choosing the best type, tone, sequence, and framing of questions and for deciding what and how much information to share to reap the most benefit from our interactions, not just for ourselves but for our organizations.
